To all whom, it may concern:

Be it known that HENRY Gr. Monsn, de-

ceased, late a citizen of the United States of America, residing in thecity and county of Philadelphia and State of Pennsylvania, did inventcertain new and useful Improvements in Portable Tools for Riveting orthe Like, of which the following is a true and exact description,reference being had to the accompanying drawings, which form a partthereof.

The invention relates to the construction of a portable tool adapted foruse in riveting, punching, and the like, and has for its object toprovide a simple, powerful, and accurate portable tool for suchpurposes.

The nature of the improvements will be best understood as described inconnection with the drawings, in which the invention is illustrated inwhat is believed to be its best mode of construction, and in which-Figure 1 is a side elevation of the tool; Fig. 2, a sectional elevationtaken on the seetion-line 2 2 of Fig. 1; Fig. 3, a cross-section on theline 3 3 of Fig. 1; Fig. 4, a cross-section on the line 4: I of Fig. 1;Fig. 5, a crosssection on the line 5 5 of Fig. 1; Fig. 6, a crosssectionon the lineG 6 of Fig. 1; Fig. 7, a crosssection on the line 7 7 of Fig.1; Fig. 8, aside elevation of the cross head alining device shown insection in Fig. 7. Fig. 9 is a plan view of the actuating-cylinders andcontrolling devices by means of which the levers of the improved toolare operated. Figs. 10 and 11 are sectional views of thecontrollingvalve shown in Fig. 9, showing the different positions towhich the valve is moved in the operation of the apparatus. Fig. 12 is alongitudinal section through one of the powercylinders, taken as on theline l2 12 of Fig. 9 and shown on an enlarged scale. Fig. 13 isalongitudinal section through the cylinder K, taken as on the line 13 13of Fig. 9.

A and B are the levers which constitute, so to speak, both the mainoperative devices and the frame of the portable machine. A and B are theworking ends of these levers, to which the appropriate tools, be theyriveters, punchers, or the like, are attached, such tools beingindicated at E and E, A and B indicating opposite ends of the levers, towhich power is applied to operate the tools.

A and B are pivotal bearings formed in the intermediate portions of thelevers and in which are situated pivot-pins C C, to the ends of whichare pivotally connected the links C C, which connect the two leverstogether by connecting the pivot or fulcrum pins about which they turn.

In order to secure at all times the proper alinement of the levers andthe operative tools supported on their ends, it is evident that somedevice other than the links C C must be employed, and, by preference,the two levers are connected by a sliding cross-head which willeffectually prevent any relative shifting which would destroy the properalinement, and, by preference, this sliding crosshead is placed in theline of action between the pivot-pins C C. In the drawings arerepresented arms D D as extending inward from the lever A, said armsbeing provided with pin-bearings, (indicated at D D,) and another arm Dis shown extending inward from the lever B and between the lovers D D,and in which is formed a cross-head guideway, (indicated at D",) andthese lapping arms are connected by means of a sliding cross-head Dworking in the guideway D and having laterally-extending pivot-pins D Dsupported in the pin-holes D of the arms D. It will readily be seen thatthis connection in no wise interferes with the pivotal movement of thelevers, while at the same time it efi'ectually prevents any variancefrom correct alinement.

In the end A of the lever A is formed a pin-hole, (indicated at A,) inwhich is placed a pivot-pin F, to the ends of which are pivotallyconnected the arms F F, a plunger-piston, (indicated at F and to the endB of the lever B is connected, by means of a wedge G passing through aperforation B in said leverarm and through perforations in the arms GGr, a cylinder G connected with said arms G, and in which theplunger-piston F works, G indicating a port for fluid under pressureentering the bottom of the cylinder G H and h are cylinders secured tothe leverarm B and of identical construction. Similar parts are markedwith the same letters, except that in the one the capitals are used andin the other the small letters. Except, therefore, where it is necessaryto speak of both cylinders reference shall be madeonly to the cylindermarked H.

H indicates the rear head of the cylinder, having in it a port,(indicated at H H indicates the front head of the cylinder, to which issecured an extension H and the stufling-box, (indicated at 11 Hindicating the gland by which the packing is tightened. The extension H*has fitted to its bore (indicated at H) a grooved cylindrical sleeve Hin which the piston-rod to be hereinafter described fits and whichforms, in effect, the extension proper of the cylinder H. In front ofthis the extension is continued, as indicated at H of somewhat largerdiameter than the piston-rod.

H indicates a port through the extension H", registering with the port Hin the cylindrical sleeve H and H" indicates a port entering theextension H H indicates a grooved ring screwing into the endv of theextension H" and serving as an abutment for the packing held in place bythe gland I is a piston working in the cylinder H and having apiston-rod I, which is also a plunger piston working through thestuffing-box H and fitting in the cylindrical extension H As shown, thecylinders H and /z are secured to the lever-arm B by the devices bestshown in Figs. 5 and 6, the front ends of the cylinders bearing againstblocks (indicated at JV") and being held thereto by straps, (indicatedat J 1") while the rear ends of the cylinders are grasped, as shown inFig. 6, between straps J j and J j.

J and J 6 indicate straps extending over the inner upper face of thelever-arms B and serving as supports for the cylinder K, which isclamped thereto by the straps J and J This cylinder K (best shown inFigs. 9 and l3)has a head K with a port K formed in it and a head K witha port K" formedin it and is provided with a loose piston, (indicated atL,) which is free to move in either direction,

M M are arms bolted to the end A of the lever A, as well shown in Fig.4:, and supporting on the inside of said lever-arm a pivot-pin M, towhich is pivotally attached the piston-rod M secured in turn to thepiston l N N are arms securely bolted to the leverarm B and supporting,through trunnion-like pins N N, secured in bearings N a cylinder Nhaving, as shown, a port N at its upper end.

O is a conduit for pressure fluid having outlet-passages at O and thefirst connecting with the pipe 0, which in turn connects with the port Pof the casing of a valve, (indicated at P,) said val ve-casing havingalso ports, as indicated at P P P, the latter connecting with anexhaust-pipe 0 The port P connects, through a pipe 0, with the port K atthe rear end of the cylinder K, and the port P connects, through a pipe0" and its branches 0 0 with the ports H it of the cylinders H it.

Q is a valve adjustable in the casing of the valve P, Q, indicating thelever by which the valve is turned.

The port O of the conduit 0 connects, through the pipe indicated at 0with the port N of the cylinder N R is a pipe leading out of the frontend of the cylinder K and connecting, through branches R r, with theports H lb of the cylinder extensions H it.

B r are pipes connecting with the ports H" /t" and both connecting,through a pipe R with the port Gr and the cylinder G".

T, Figs. 1 and 2, is the bail by means of which the tool as a whole issupported from a convenient means of transporting it to a place of use.

In operation the tool 0, suspended from the bail T, is transported tothe place of use and the dies or other devices E E properly adjusted inconnection with the work. The valve Q is normally in the position shownin Fig 9, with the pipes O and 0 connected with the exhaust 0 In thisposition the pistons I will be retracted, as shown in Fig. 12, and thepiston L will also be retracted to a position depending on the amount offluid with which the front end of the cylinder K is filled. The pressurefluid from the conduit 0 being admitted freely to the cylinder N theends A B of the levers A B will be drawn together as far as they arepermitted to go. The operator then turns the valve Q to the positionshown in Fig. 10, permitting pressure fluid to pass from the conduit 0through the conduit 0" and thence into the rear end of the cylinder K,pressing forward the piston L against the oil or other fluid containedin the front end of the cylinder, this oil passing through the conduitsR 1" into the extensions H /L10 and H 72, and through the pipeconnections R and r and R to the bottom of the cylinder G and the areaof the piston is such that the pressure of the piston in the cylinder Gwill overcome that in the cylinder N causing the arms A and B to moveapart and the arms A B to move together until the tools supported on thelast mentioned arms come in contact with the work. The operator nextturns his valve to the position shown in Fig. 11, placing the conduit 0also in connection with the fluidpressure supply and connecting the rearends of the cylinders H it with said supply, which then acts upon thepiston I t', forcing their pistons and plunger extensions 1 forward.Said plunger in moving forward first forces acertain quantity of thecontained fluid back through the pipes R and a to the cylinder K andthen closes the port H, its further forward motion pressing the fluidout through the conduits R 1' &c., into the cylinder G which then actswith the force due to the increased area of the pistons I and '2",exerting the necessary working pressure upon the tool supported on thelever-arms. The work of punching, riveting, or the like being thusaccomplished, the operator again turns the valve Q to the position shownin Fig. 9, putting the rear ends of the cylinders H, h, and K inconnection with the exhaust, whereby the constantlyacting power of thecylinder N will again bring the arms together, the fluid in the cylinderG flowing back into the cylinder K.

It will of course be obvious that a single cylinder H will work inexactly the same way as the two cylinders H [1,, the division being forpurposes of convenient application and economy of space.

Having now described the invention, what is claimed as new, and desiredto'be secured by Letters Patent, is
